Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.

Accessory belt tensioners provide tension to the belt drive system, ensuring the belt is able to properly turn engine accessories without slipping. If your tensioner has failed, replace it with a brand-new unit to ensure proper water pump and alternator functionality.
